Issued at 213 PM CDT Wed Jul 17 2024
Tonight and Tomorrow...
Afternoon global guidance highlights a 1023mb sfc high across the
Northern Plains making its way east towards the Ohio Valley Region
tonight. This will allow for a trough axis to sink into the
southeast region from the north. Rain/storm chances will begin to
increase across central MS heading into the overnight period as the
aforementioned trough sinks further south. HREF guidance is hinting
at some fog potential south of I-20 later in the overnight period.
The combination of increasing cloud cover and mid to high PoP
chances (between 40-65%) will cause nighttime temperatures to drop
in the low 70s across our CWA. Heading into Thursday, the upper
ridge will begin to fully break down as a broad trough dips
southward, bringing a frontal boundary into the region. Showers and
storms increase Thursday morning and afternoon hours as the frontal
boundary stalls across our forecast area. Areas south of I-20 will
likely see heat indices between 105-108 degrees, due to
compressional heating and moisture pooling ahead of the front.
Because of this, we went ahead and issued a Heat Advisory for
portions of south MS and portions of northeast LA. The advisory will
go in effect starting around 10 AM Thursday morning to 7 PM Thursday
evening. A "Limited" threat for increasing heat stress has been
introduced in our HWO for these areas, especially where the Heat
Advisory is in effect. /CR/
Thursday night through mid next week...
The long term period will be dominated by a slightly cooler and
wetter regime with persistent southwest flow. A strong midlevel high
over the western CONUS will drive a midlevel trough and associated
surface cold front south into our area. Thursday night into Friday,
this front stalls out in the vicinity of the Pine Belt and will
serve as the main focus for locally heavier rainfall through the
period. Boundary parallel flow and PWATs in excess of 2 inches will
favor training storms with efficient rain rates. While beneficial in
light of recent dry conditions, this could potentially lead to some
localized flash flooding in this area, especially given the
persistence through the period. However, with the dry conditions
and potential for rain to be spread out over time, confidence in a
greater flash flood scenario is low at this time. Temperatures in
the wake of the front with be around 3 to 5 degrees below normal
(85- 90), which will be a welcome relief for many. Early next week
building high pressure to the southeast will push moist Gulf air
back north towards the I-20 corridor. Temperatures warm slightly
and rain will become more numerous across the area. A persistent
barrage of rain is likely to continue through the period with
current estimated totals between 2 to 4 inches. Conditions will
continue to be monitored, so check back on future forecasts for
updates./SAS/

.AVIATION...
(00Z TAFS)
Issued at 723 PM CDT Wed Jul 17 2024
SHRA and TSRA will affect portions of the forecast area throughout
the TAF period, with the chances for gusty winds near storms and local
reductions in visibility being the primary hazards for aviation
during the period at most sites. Some low stratus or patchy BR is
possible as well in a few areas, with MVFR conditions possible
especially near areas that receive rainfall before 12Z Thursday.
Scattered SHRA and TSRA generally expected across the area by 18Z
Thursday. /NF/
